IMPROVEMENT IN HOLDBACKS FOR VEHICLES.

Specification forming part of Letters Patent No. 146,042, dated December' 30, 1573; application filed October 8,1873.

To all who-m t may concern Be it known that we, H. M. BURDICK and MosEs R. FLANDERS, of Ilion, in the county of Herkimer and State of New York, have invented certain Improvements in Holdbaoks shown in section. Fig. 2 is a transverse section on the line x x of Fig. 1. Fig. 3 represents the part B, detached and slightly modined.

In constructing our device, we provide a base-plate, A, having a raised portion, O, on its upper face, as represented in Figs. l and 2; this portion O being slotted longitudinally and vertically, forming, as it were, two verticallyprojecting ears, on the inner face of each of which there is formed a longitudinal groove, o, as represented in Figs. 1 and 2. We then provide a piece, B, which has an elongated hole to receive the breeching or holdback strap at its upper end, the lower end being of a thickness to fit in between. the ears of plate A, and having projecting laterally from each side a round lug, a, as shown in Figs. 1, and'2, these lugs being ofi a size to slip into the grooves o on the inner sides of the projecting portion C of plate A. Through plate A, at its center, is made an opening, e, and the lower end of the piece B is of such a length that when inserted or connected to plate A, as shown in Figs. 1 and 2, it will project down into this hole 6, and thus prevent it from slipping out until turned over, as represented by the dotted lines of Fig. 1. As shown in the left-hand ligure of Fig. 3, the part B may be slit lengthwise, and the parts sprung asunder, as shown, which will cause them to hold in place when inserted in the grooves o of plate A, thereby preventing it from becoming acci-y,

dentally detached.

In using our device, theV plate A is secured upon the thill,'and the part B is secured to the harness by being attached to the holdbackstrap. The part B, being held in the position indicated by the dotted lines-that is, turned over forward-is then shoved backward until its lugs a are secured in the grooves o, when it is swung over back to lthe position shown in Fig. l, when its lower end engages in the hole c, and prevents it from slipping out. To unfasten it the part is swung over forward and drawn out or off, as the case may be.

By this construction we provide a simple and efficient device that can be easily attach ed or detached, and which, in ease the traces become detached and the horse runs away, will at once become detached automatically by the projections O, in combination with the loop B,

provided with the lugs a, all constructed and combined to operate substantially as described.
